I've been using Simple Green in various dilutions throughout my car (2000 Civic SI) (not on the dash, though, here I've used a little bit of unscented Dove soap (neutral ph, I've read), swished in some water, and then promptly rinsed/wiped with clean water, following with 303). I was looking at EFHI for use on my wheels, tires, and interior (in appropriate concentrations), but I wanted to buy from the Autopia store, and they don't seem to sell the EFHI. Can someone recommend something that the Autopia store sells that compares to the EFHI, that can be used on wheels, tire, interior plastics (not clear), and my dash? Is there a citrus-based cleaner that's sold in Costco that would be safer than the Simple Green, if not as good as EFHI? Thanks.
